Question 43664
Use the midpoint formula.   It is the same as finding the average of x and the average of y:

(x1 + x2)/2 will give the x value.
.
(y1 + y2)/2 will give the y value.
.
Plug in the values:

(x1, y1) = (-2, 9)
. 
(x2, y2) = (4, 5)

.
[(-2 + 4)/2 , (9 + 5)/2] = Midpoints [(2/2), (14,2)] = (1, 7) as the midpoint.
